I was following a few tutorials on Kubernetes and on Minikube for three days now on my laptop, I was completely new to Kubernetes, Docker, Minikube, and got to the point where my deploys/replicas/services (I am still having a lot of confusion between them) are available to curl, both by using a "common" virtual IP and individual IP of each replica. But, unfortunately, I can only curl them from "inside the cluster" (if that is a correct term) in other words only after I type minikube ssh.
Now, how do I get my "hello world" app available from the outside, i.e. From the host machine or machines connected via LAN/WAN (for example that would be lovely to open the app URL in the phone's browser and see the JSON output).
You can view the services in your minikube cluster via minikube service list. If you assigned a NodePort to a service there will be an URL displayed which you can access from your host, e.g. the Kubernetes dashboard:
minikube service list
|-------------|----------------------|----------------------------|
| NAMESPACE | NAME | URL |
|-------------|----------------------|----------------------------|
| default | kubernetes | No node port |
| kube-system | kube-dns | No node port |
| kube-system | kubernetes-dashboard | http://192.168.64.67:30000 |
|-------------|----------------------|----------------------------|
Access from the rest of your network is of course only possible when your virtual machine is bridged into it.
